Throw it in a 2x2 stone pin with 1 (2 for safe keeping) doorframes all around as walls and use a Argi to pick it up and put it in and use whatever tranq to knock it... If u have no Argi just launch tranqs at it and run away it is not fast so it won't catch up
1. Get tranq arrows and a crossbow
2. Find an anky of your desire
3. Shoot it in the head while walking backwards (they're slow so you can just walk while shooting)
4. When it runs away chase after it and shoot it
5. It'll be knocked out.
6. Feed it recommend food and any narcos if needed.
They get about 3x more metal than you! And depending on the level they can easily kill Raptors and other small predators.
They're found almost everywhere
Beaches, highlands, chalk hills, green forest, I've even see some near desert.
